Can't select certain items

[joet082964]

I'm a semi-seasoned INDD user, but this has me stumped.

I have lines on a page that I can't select.

I have tried all these solutions:

• Override all master page items has no effect - still can't select the lines
• The lines are present in the assigned master page and I can select them there
• I checked layers - none are locked but one of the layers turns off the lines I can't select
  • None of the individual objects in the layers palette will turn the lines off
  • I can only turn off the layer visibility of the lines in question of the "parent" layer
• No objects on the page are locked
• If I create a new page and assign the same master, I can override master items on that new page and delete lines there

Any ideas on other things can affect the ability to select items on a page?

I was not able to make his suggestion work but I did find a workaround mentioned in my last set of screen shots.

Check the SUB-layers. 

1. Expand the sublayer

2. Unlock any locked sublayers
